The project implementation plan can be divided into two categories:
One is the construction of a small smelter according to the proposed process flow specifically for the treatment of friendly catalysts;
The second is to use the process and equipment of the existing Ba metal smelter to enrich the extraction of the Min metal in the non-ferrous metal smelting process.
Wet leaching of precious metals: The essence of wet technology is to use hydrochloric acid + strong oxidant or with other special chemical reagents (such as cyanide), directly from the carrier to dissolve the aluminum group metals, and then from the low concentration bath to further enrich and extract the platinum group metal products.
Various fire hydrometallurgical techniques are currently being studied for the recovery of platinum group metals. However, the process complexity, technical and economic indicators, engineering implementation difficulties, environmental protection and other aspects of the various methods vary greatly.
